  Heteroaromatic and Aniline Derivatives of Piperidines As Potent Ligands for Vesicular Acetylcholine Transporter

  摘要：

  To identify suitable lipophilic compounds having high potency and selectivity for vesicular acetylcholine transporter (VAChT), a heteroaromatic ring or a phenyl group was introduced into the carbonyl-containing scaffold for VAChT ligands. Twenty new compounds with ALogD values between 0.53 and 3.2 were synthesized, and their in vitro binding affinities were assayed. Six of them (19a, 19e, 19g, 19k, and 24a-b) displayed high affinity for VAChT (K-i = 0.93-18 nM for racemates) and moderate to high selectivity for VAChT over sigma(1) and sigma(2) receptors (K-i = 44-4400-fold). These compounds have a methyl or a fluoro substitution that provides the position for incorporating PET radioisotopes C-11 or F-18. Compound (-)-[C-11]24b (K-i = 0.78 nM for VAChT, 1200-fold over sigma receptors) was successfully synthesized and evaluated in vivo in rats and nonhuman primates. The data revealed that (-)-[C-11]24b has highest binding in striatum and has favorable pharmacokinetics in the brain.

  Bipiperidinyl compounds and salts thereof are disclosed. The compounds include high affinity ligands for σ 1 receptors. Some compounds are also highly selective for σ 1 receptor compared to σ 2 receptor. Compounds can comprise radioisotopes, including 18 F or 11 C. Radiolabeled compounds can be used as probes for imaging distribution of σ 1 receptor in a subject such as a human using positron emission tomography (PET) scanning.

  Suzuki-Miyaura cross-couplings of amides offer an approach to the synthesis of ketones that avoids the use of basic or pyrophoric nucleophiles. However, these reactions require glovebox manipulations, thus limiting their practicality. We report a benchtop protocol for Suzuki-Miyaura cross-couplings of aliphatic amides that utilizes a paraffin capsule containing a Ni(0) precatalyst and NHC ligand. This

  酰胺的 Suzuki-Miyaura 交叉偶联提供了一种避免使用碱性或自燃亲核试剂的酮合成方法。然而，这些反应需要手套箱操作，从而限制了它们的实用性。我们报告了脂肪族酰胺的 Suzuki-Miyaura 交叉偶联的台式方案，该方案利用含有 Ni(0) 预催化剂和 NHC 配体的石蜡胶囊。该方法范围广泛，可扩展，并提供了一种用户友好的方法将脂肪酰胺转化为烷基芳基酮。

Moreover, a gram-scale Suzuki–Miyaura coupling/Fischer indolization sequence demonstrates the ease with which unique polyheterocyclic scaffolds can be constructed, particularly by taking advantage of the enolizable ketone functionality present in the cross-coupled product.

  我们报告了镍催化的脂族酰胺衍生物的Suzuki-Miyaura偶联。先前的研究表明，脂族酰胺衍生物可以经历Ni催化的碳-杂原子键的形成，但是使用脂族酰胺衍生物形成Ni介导的C-C键仍然很困难。本文公开的偶联相对于基于酰胺的底物和硼酸酯偶联配偶体都容许相当大的变化，并且在存在杂环和可差向异构的立体中心的情况下进行。此外，克级的Suzuki-Miyaura偶联/ Fischer吲哚化序列证明了构建独特的多杂环支架的简便性，特别是利用了交叉偶联产物中存在的可烯化的酮官能团。
